In this paper, we propose a dual pulse repeated frequency (dual-PRF) waveform design of time-division ISAC (TD-ISAC) based on a 5G new radio (NR) communication system using downlink communication slots. We choose time-division mode to design waveform to avoid the interference between sensing and communication. Embedding sensing functions in a 5G NR system, we design a dual-PRF sensing slot to satisfy the constraints of common channel and uplink communication. Considering two uplink modes, namely flexible and fixed, we design two dual-PRF waveforms and illustrate the sensing theory performance of the designed waveform by the ambiguity function. Then, we exploit the designed waveform to the vehicle parameter estimation. To verify that the designed waveform has good adaptability to different signal processing methods, we realize the parameter estimation by two types of methods: the discrete Fourier transformation-based method and the compressed sensing-based method. At last, we verify the effectiveness of the designed waveform system by simulation experiments and real traffic scenarios.<\/jats:p>","DOI":"10.3390\/s23239463","type":"journal-article","created":{"date-parts":[[2023,11,28]],"date-time":"2023-11-28T07:41:32Z","timestamp":1701157292000},"page":"9463","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Dual-Pulse Repeated Frequency Waveform Design of Time-Division Integrated Sensing and Communication Based on a 5G New Radio Communication System"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2953-8018","authenticated-orcid":false,"given":"Ping","family":"Chu","sequence":"first","affiliation":[{"name":"College of Electronics and Information Engineering, Shenzhen University, Shenzhen 518060, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2410-167X","authenticated-orcid":false,"given":"Zhaocheng","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Electronics and Information Engineering, Shenzhen University, Shenzhen 518060, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-1437-898X","authenticated-orcid":false,"given":"Jian","family":"Zheng","sequence":"additional","affiliation":[{"name":"College of Electronics and Information Engineering, Shenzhen University, Shenzhen 518060, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,11,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11068","DOI":"10.1109\/JIOT.2023.3235618","article-title":"Integrated Sensing and Communication Signals Toward 5G-A and 6G: A Survey","volume":"10","author":"Wei","year":"2023","journal-title":"IEEE Internet Things"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"68","DOI":"10.1109\/MCOM.001.2200420","article-title":"A General Channel Model for Integrated Sensing and Communication Scenarios","volume":"61","author":"Zhang","year":"2023","journal-title":"IEEE Commun.
